Tungsten alloy geological drill tube is a kind of tungsten alloy tube used for core drilling by the geological department. It also is a long-length tungsten alloy tube for geological drilling with hollow section and no joints around it. It has high strength, high hardness, good wear resistance, high impact toughness, good corrosion resistance and so on.

Since the drilling tube is to be drilled to a depth of several kilometers, the working conditions are extremely complicated, and the drill tube is subjected to stress such as tension, pressure, bending, torsion and unbalanced impact load, which is also subject to mud and rock wear. Therefore, the tube must have sufficient strength, hardness, wear resistance and impact toughness, and tungsten alloy geological drill tube can meet this requirement.
